In outdoor drilling, downhole, and pump applications, machinery needs to be durable enough to withstand extreme environmental conditions, chemical exposure, and abrasive contaminants. At APM Hexseal, we build long-lasting, reliable seal solutions that can protect against the rigors of outdoor drilling, downhole, and pump applications. Learn more about how our products protect various machinery from the hazards of these operations.

APM Hexseal’s Sealing Solutions

Drilling machinery needs to be able to withstand exposure to environmental extremes while operating at peak levels. Equipment sealing solutions must protect against factors such as:

  • Environmental hazards: dirt, mud, dust, moisture, water exposure, high and low temperatures, UV radiation, ozone, and weathering
  • Chemicals: corrosive substances, hydrocarbons, oil, and contaminants
  • Mechanical hazards: abrasion, high pressures, vibration, and shock

Protecting pump and drilling equipment is critical for maintaining uptime and productivity. APM Hexseal’s sealing solutions are built to protect machinery in these tough applications. Some common sealing applications are:

  • Cameras and controllers
  • Control panel protection
  • Downhole tools
  • Drill rigs
  • Electrical connector seals
  • Hydraulic system protection
  • Mud pumps
  • Pressure and temperature sensor seals
  • Valve and actuator seals

Sealing Boots & Bushings

Boots and bushings work together as parts of a comprehensive sealing solution. Bushing seals are sleeves that fit around mounting holes and other circular openings to limit intrusion from contaminants. Boots are molded components made from flexible materials like rubber that sit over switches, where they provide an impenetrable barrier so contaminants can’t penetrate into the electronic panel.

At APM Hexseal, we design and develop sealing components to withstand extreme environmental conditions and provide long-lasting protection to otherwise vulnerable machinery. Our sealing products for drilling, downhole, and pump applications include:

  • Boots:
    • Push-button switches
    • Toggle switches
    • Rotary switches
    • Rocker switches
    • Circuit breakers
  • Bushings:
    • Switch panel cut-outs

Sealing Hardware

When selecting protection hardware, it’s important to choose products that are properly rated or developed for specific environmental conditions. APM Hexseal designs and manufactures purpose-built sealing solutions for downhole, drilling, and pump applications.

Seelbolts® and Seelskrews®

Our reusable Seelbolts® and Seelskrews® create a dependable seal that can be installed, reinstalled, and reused without additional chemical sealing compounds. These fasteners feature high-quality weatherproof materials to create a long-lasting, leak-free seal.


These self-sealing nuts are easy to install and reinstall, and we offer a wide range of sizes for easy compatibility with standard studs, bolts, and screws. They are also built for extreme conditions, such as temperatures ranging from 103 °F to 400 °F.


Jumbo-sized, reusable Nutzilla sealing nuts are one-piece components available in sizes up to M90. We construct them with the same innovative metal-to-rubber bonding process as our other sealing products. Nutzilla provides an easy-to-install, reliable seal for oversized equipment. Each Nutzilla has a shelf life of 25 years.

Seeloc® Washers

These washers have a continuously ridged silicone contact surface that creates an effective, reliable seal. Once the washer face gets compressed by the fastener, the silicone creates an airtight seal against the mating surface and the thread of the fasteners.

Benefits of APM Hexseal Products

APM Hexseal’s sealing products offer unique advantages for harsh industrial operations, including drilling, downhole, and pump applications. These benefits include:

  • Long-lasting durability: Our sealing hardware protects equipment from degradation due to environmental factors like extreme temperatures, chemical exposure, moisture, road salt, dust, dirt, mud, and more.
  • Enhanced vibration and pressure resistance: Our Seelbolts® and Seelskrews® are engineered to withstand the effects of prolonged vibration and pressures that might otherwise loosen the seal.
  • Cost-effective: Because our sealing solutions are reusable, they are cost-saving products that our customers can trust to provide a reliable seal everywhere they are installed.
